We had a nurse tell us how much the medical education/training had changed in the fifty years she was on the job. She said when she was in school you were trained to actually diagnose systemic causes but for the past thirty or so years she said many times medical staff just determine which drugs best lessen the symptoms. It really frustrated her. Thanks! I wish we had more of a chance to walk in the grass during our brief summers, thankfully we have access to these other devices.
